The spec is a little ambiguous, isn't it? But the intended effect is the empty string, if the original string consists of nothing but whitespace characters. This case should probably be clarified in XPath 2.0's functions ( http://www.w3.org/TR/xquery-operators/#func-normalize-space ) > In this case it would be nice to be able to test for some whitespace as > opposed to an empty string. test="string() and not(normalize-space())" would tell you if the string's not empty and that it is empty when its whitespace is normalized. - Mike ____________________________________________________________________________ mike j. brown | xml/xslt: http://skew.org/xml/ denver/boulder, colorado, usa | resume: http://skew.org/~mike/resume/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
